Release notes

This page provides a high-level summary of releases starting from 2025. It details new functionality, UI changes, deprecations, and important announcements across Unleash and its components.

Each release note is tagged with the part of the product it applies to. Use the tags to filter for the areas you’re interested in.

  • Unleash: The core platform, including the Unleash server, the Admin UI, and overarching product decisions and announcements. See the architecture overview.
  • Enterprise Edge: Releases for Unleash Enterprise Edge, a lightweight caching layer that improves the scalability, performance, and resilience of your feature flag infrastructure.
  • MCP server: Releases for the Unleash MCP server, which lets AI coding assistants manage feature flags.
  • SDKs: Changes that affect the Unleash SDKs, such as naming changes or new capabilities that span multiple SDKs.

A single release note can carry more than one tag when a release touches several areas.

Unleash follows semantic versioning, with major versions (for example, v7.0.0) including significant new features and might include breaking changes, and minor versions (for example, v7.4.0) adding new functionality while maintaining backward compatibility.

For a comprehensive list of all Unleash releases, including patch versions and history prior to 2025, visit the Unleash Releases page on GitHub.

The Unleash MCP server, Unleash Enterprise Edge, and each SDK are versioned independently and publish their own changelog in their respective GitHub repositories.

MCP server v0.3.0

Unleash MCP server is now generally available

The Unleash MCP server is now generally available. It gives your AI coding assistants a structured contract for managing feature flags safely, guiding them through evaluating risk, creating flags, wrapping code, and cleaning up after a rollout. It works with tools like Claude Code, Cursor, GitHub Copilot, Kiro, and OpenCode.

New tools to list flags and projects

Two new tools let assistants discover and audit your feature flags directly:

  • list_projects lists all Unleash projects available to your token.
  • list_flags lists the feature flags in a project, with support for filtering, ordering, and pagination.

These tools power agentic flag-audit workflows and back the detect_flag inventory analysis, so assistants can enumerate flags before creating new ones or identify cleanup candidates. For details, see the tool reference.

Remote MCP server in beta

You can now connect MCP clients to a remote MCP server hosted by your Unleash instance, without installing anything locally. This is useful when developers cannot run MCP servers on their machines, or when you want to manage MCP access centrally. The remote MCP server is in beta. See Enable the remote MCP server for setup steps.
